This was my first Android (Java) and iOS (Objective-C) applications, and they are up and running still today, even though they were updated by company internal developers lately, they were mostly redesigned visually.
I take it as proof that I can write code that is understandable and maintainable for long term support and by others.
This applications are quite simple, far simpler then my latest ones, but they were ideal to start up my full time freelancer and independent developer path.
